Abstract

Ce matériau est constitué parun mortier comprenant des granulats d'un composé minéral du bore, par exemple de la colémanite, du ciment alumineux et de l'eau liée chimique­ ment, la teneur en bore dudit mortier étant d'au moins 0,62.10²² atomes/cm³ et la teneur en hydrogène dudit mortier étant d'au moins 1,42.10²² atomes/cm³.
Il est utilisable pour la réalisation de murs-écrans, de revêtements et d'éléments d'installation pour l'obtention d'un milieu sous-critique.
